[Algesic phenomena in panic disorders].

There were examined 35 patients with panic disorders (PD) which were divided into 2 groups. In patients of the 1-st group there were observed headaches of tension type (17 individuals), meanwhile in the patients of the 2-nd group (18 cases) there weren't observed any algesic syndromes. A "saturation" of the life of a patient with the different algesic phenomena were estimated as well as the level of a depression according to Beck's scale and the manifestations of psychopathologic symptoms according to SCL scale were also studied. To estimate neurophysiologic parameters there were used a method of a contingent negative deviation (CND) and nociceptive flexor reflex. For the patients of the 1-st group there was quite characteristic a "saturation" of life with algesic events, an atypicity of the algesic attacks and more pronounced connection of PD debut with biologic but not with emotional factors. Psychometric observation revealed a significantly higher levels of both the depression according to Beck's and the somatization according to SCL scales as compared with the 2-nd group. Alterations in CND parameters (a decrease of the amplitude of the late wave, increase of postimperative negative wave) and an increase of a subjective algesic perception in the patients of the 1-st group had testified the pronounced desadaptive disorders. In the patients of the 2-nd group these indices were normal. Thus, on the PD model there were studied some psychophysiologic factors, which caused a formation of chronic algesic syndromes in the patients.
